Product overview :
Perhaps your web is abrasive enough to scratch the surface of steel idlers. Or maybe the caustic vapors of your coating operation likes to pit and corrode aluminum rolls. And it would not be unusual if your coated web was causing some trouble by sticking just a little too much to certain rolls in the line.
These are typical challenges where custom roll coatings and platings are used successfully every day to improve web handling. The real challenges, however, are much more numerous. Likewise, the custom solutions Webex has to offer are quite varied and unique.
Here you’ll find some of the more common coating and plating options used today to meet the challenge of unique environments, webs and converting processes. This overview is meant to provide an initial understanding of solutions that may work for you. For professional assistance in selecting the best possible option, talk to our Customer Support Specialists. They have the experience and expertise to properly shape your decision.
